A large tentiform mine on the underside of a leaf, with many small longitudinal folds. The mine extends a large area from the main vein till the leaf margin. The sides of the mine are whitish because the parenchyma is consumed, leaving a green patch in the center. In rare cases, more than one mine occur on one leaf, but then the leaf is contorted. The dark frass is concentrated in one corner of the mine.
